Subject [jira] [Commented] (MAPREDUCE-3913) RM application webpage is unresponsive after 2000 jobs
Date Fri, 24 Feb 2012 17:39:49 GMT

    [ https://issues.apache.org/jira/browse/MAPREDUCE-3913?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13215767#comment-13215767
] 

Jason Lowe commented on MAPREDUCE-3913:
---------------------------------------

Problem may have been introduced with MAPREDUCE-3754.  Ajax data URL was designated as cluster/apps/json
but anything after cluster/apps/ is interpreted as an application state.

Not sure the Ajax support is useful anymore, as the app table always is sorted on the client
and therefore the client always grabs all the data from the server.  Seems like we could just
drop the Ajax loading support and leverage the existing JS_ARRAY rendering and end up with
the same thing.
